How to fix jagged edges on conic-gradient

Question

I got a progress bar that I build using conic-gradient, but its edges look not sharp. I've found some suggestions online but none of them seem to work so far. Here is the fiddle of the whole progress bar.

 background-image: conic-gradient(
    transparent var(--min-degrees),
    #00ACEE var(--min-degrees) var(--progress, 0),
    transparent var(--progress, 0)
  );

Any idea how I can smooth its edges?

Thanks
